MAP4KE18A

MAP4KE18A is a kind of transient voltage suppressor (TVS) diode. It is specifically designed to protect integrated circuits (ICs) and other sensitive electronic components important from electrostatic discharges (ESDs), power supply transients, and other forms of inductive switching. It is a unidirectional device featuring low-clamping voltage and fast response times during transient conditions. As a high-efficiency device, it offers maximum protection with minimal dissipated power.

The MAP4KE18A’s application field includes but not limited to communication networks, computers, consumer electronics, automotive, and industrial electronics. It offers protection from voltage spikes, transients, ESDs, and inductive switching.

Working Principle

MAP4KE18A is a unidirectional TVS diode possessing a low on-state Resistance which helps it to handle high voltage/current pulses with minimal power dissipation. When a voltage at the input port exceeds the breakdown voltage (Vbr) of the device, the MAP4KE18A diode quickly turns on and begins to conduct. The device functions as a clamp limiting voltage at the breakdown voltage level, therefore, preventing damage to the connected device. The device has a bypass diode connected in series with the diode which provides discharge path to the leakage current.

The MAP4KE18A device can absorb high energy pulses up to 1000W if the applied voltage and current waveform is low in amplitude. The device is designed to limit voltages to the breakdown voltage level and absorb transient energy which could otherwise damage ICs or other sensitive components. The device has a fast response time of less than 1ns.

Conclusion

MAP4KE18A is a unidirectional device featuring fast response times and a low on-state resistance. It is specially designed to protect integrated circuits (ICs) and other sensitive electronic components from ESDs, power supply transients, and other forms of inductive switching. It has broad application fields including consumer electronics, communication networks, computers, automotive, and industrial electronics. It is a high-efficiency device that offers maximum protection with minimal dissipated power.
